Diego Biurrun	1e9c5bf4c1	asm: FF_-prefix internal macros used in inline assembly These warnings conflict with system macros on Solaris, producing truckloads of warnings about macro redefinition.	9 years ago

Pedro Arthur	6de58b4903	swscale: cleanup unused code Removed previous swscale code under '#ifndef NEW_FILTER' and removed unused fields of SwsContext	9 years ago
Michael Niedermayer	3b905b9fe6	swscale: Deprecate vector functions which are unused outside swscale There are no known users of these functions within debian It should be thus possible to remove these functions without recommandition of a replacement Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	67e5bd0c50	swscale/utils: Fix chrSrcHSubSample for GBRAP16 Fixes part of Ticket5264 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Derek Buitenhuis	21f9468402	avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago

Ganesh Ajjanagadde	c8905e0d67	swscale/utils: replace pow by exp2 exp2 is a faster function. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Michael Niedermayer	325b59368d	swscale/utils: Fix for runtime error: left shift of negative value -1 Fixes: c106b36fa36db8ff8f3ed0c82be7bea2/asan_heap-oob_32699f0_6321_467b9a1d7e03d7cfd310b7e65dc53bcc.mov Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Andreas Cadhalpun	e8c3716064	swscale: rename sws_rgb2rgb_init to ff_sws_rgb2rgb_init It is an internal swscale function and thus should not be exported. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	9 years ago
Andreas Cadhalpun	8bfbc8c5e5	swscale: rename sws_context_class to ff_sws_context_class It is an internal swscale symbol and thus should not be exported. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	9 years ago
Ganesh Ajjanagadde	26e8895b73	all: add _DEFAULT_SOURCE locally wherever needed Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE. The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros. This solution is on the lines of the one in commit `af1818276e`.

Michael Niedermayer	d730dd8c53	swscale: Forward colorspace updates to the 2nd cascaded context in case of alphablend The first just does the blending and wouldnt do anything with the colorspace values Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	21c7272859	swscale/utils: Forward luma range to the cascaded context for alphablending Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	319898bba2	swscale/utils: handle gray+alpha formats like gray for luma ranges Its illogic to handle gray differently depending on the existence of an alpha channel Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	8e05f9217a	swscale/utils: Split scaling if possible and yuv->yuv with different matrixes is requested This uses a RGB intermediate, a more optimal solution would be to perform the rematrixing directly in subsampled YUV, this is quite a bit more complicated though Fixes Ticket4805 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
